Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To solve problems of incomplete regions at the time of start and completion of printing to maintain the high quality of image by a method wherein an auxiliary scanning control means effects auxiliary scanning over a first auxiliary scanning distance which is m times a dot pitch just after the start of printing and just before the completion of printing, while it effects auxiliary scanning of other times over a second auxiliary scanning distance which is n times the dot pitch. SOLUTION: A print head 13 has N pieces of dot forming elements 51-5n arranged in an auxiliary scanning direction Y and the elements are arranged at regular intervals of (k) dots. And the head moves in a main scanning direction X with respect to a sheet S to print a pattern of dots in a rectangular region of the sheet S covered with the elements 51-5n. When one round of main scanning is completed, the sheet S is transferred in an auxiliary scanning direction by a distance corresponding to m dots and main scanning is performed again. After such operation is performed required number of times, an ordinary interlace printing is performed over a distance of n dots. And finally, an auxiliary scanning direction transfer operation is performed again over a distance corresponding to m dots required number of times to cover the entire region to be recorded.

Title: Output buffer circuit
Inventor: MIZOMOTO HIROYUKI
IPC: H01L27/088
Filed: 1990-05-21
Abstract: PURPOSE:To obtain a high-level output voltage without being affected by manufacture deviation or the like by forming an output driving circuit and a bias generating circuit on the same LSI substrate, and always impressing a stable gate potential from the bias generating circuit to the current source of the output driving circuit. CONSTITUTION:This output buffer circuit is composed of the output driving circuits of MOS transistors 1-5 and the bias generating circuit composed of MOS transistors 6-9, voltage comparator 32 and LPF 31. When a negative side input potential V2 of the voltage comparator 32 shows a potential higher than a positive side input potential V1, the output potential V3 of the voltage comparator 32 is decreased rather than a normal state. Therefore, since the gate potential of the MOS transistor 6 in the current source, a current flowing in the buses of MOS transistors 8, 7 and 6 is decreased and a current flowing in an MOS transistor 9 is also decreased so as to decrease the potential of the V2. When the V2 is lower than the V1, the reverse operation is executed and the potential of the V2 is increased. Thus, negative feedback is applied and the gate voltage of the MOS transistor 6 is decided to always obtain the condition of V1=V2 (normal state).

Title: Superconducting transformer
Inventor: HAMASHIMA KOTARO
IPC: H01F36/00
Filed: 1990-05-23
Abstract: PURPOSE:To achieve recovery to superconduction promptly even when short-circuiting is canceled and prevent a steady heat from entering easily by using a commercial frequency and by connecting a thermal type permanent current switch in series with a main coil winding in a four coil winding structure which is equipped with the primary and secondary main coil windings and primary and secondary auxiliary coil windings which are connected in parallel with them. CONSTITUTION:A main coil winding 1 on a primary side and a main coil winding 2 on a secondary side are wound on a core 3. Thermal type permanent current switches 41 and 42 are connected in series with the main coil winding. Also, Auxiliary coil windings 11 and 21 whose leakage reactance is increased are connected in parallel with the main coil winding and the thermal type permanent current switch. These coil windings and thermal type permanent current switches are placed within a cryostat 5 and are cooled to a liquid helium temperature. When a large amount of current flows, the thermal type permanent current switches 41 and 42 are turned off for high-resistance state at the same time when quench of the main coil winding occurs. After short-circuiting is canceled, current flowing to the main coil winding is further reduced and superconductive state is recovered. The permanent current switch is recovered to be on and current flowing to the auxiliary coil winding is shifted to the main coil winding for returning to the initial steady state.

Title: Ligh timing extracting circuit
Inventor: JINNO MASAHIKO
IPC: H04B10/071
Filed: 1990-05-21
Abstract: PURPOSE:To extract a light clock signal highly stably at an extremely high speed by extracting a clock frequency from an input light signal which is modulated with a digital signal and outputting the light clock signal which synchronizes with it by the light timing extracting circuit. CONSTITUTION:The input light signal 1 which is phase-modulated by an optical phase modulator 11 with a low-frequency signal from a low frequency oscillator 12 has low-frequency side bands on the right and left sides of a bright-line spectrum. Consequently, the light signal from an optical resonator 20 which is detected by a light signal detecting means shifts in phase greatly nearby a resonance frequency and this phase variation appears as it is even when converted into an electric signal 5 by a photodetector 16. When an error signal generating means detects a phase modulation frequency component (beats between a center frequency and side bands) from the electric signal 5, a phase shift which is proportional to the difference between the resonance frequency and input light signal frequency is generated as an error signal 6, which is applied to the control pat 17 of the optical resonator 20; and the free spectrum range of the optical resonator 20 is varied slightly and so adjusted that the error signal 6 becomes zero. Consequently, the light clock signal can be obtained.

Abstract: PURPOSE:To positively detect the abnormal burning for improving the accuracy of burning control by detecting the pressure condition inside the fluid conduit that generates pulses at the time of the pulse burning, and by controlling the burning condition inside the burning chaber based on the detected signal output. CONSTITUTION:In a case where the upper limit of the pulse pressure at the time of pulse burning is set to 600-800mm.Aq, for instance, as a proper burning condition range, 600mm.Aq is memorized in a burn controller 19 as a first set value, and 800mm.Aq as a second set value. A pressure sensor 18 is disposed in a mixing chamber 3, and the burning condition of a pulse burner apparatus is controlled by the burn controller 19 based on the pressure change in the mixing chamber 3. As the condition of the pulse generation at the time of the pulse burning can accurately be detected, abnormal burning conditions such as that the upper limit of the pulse pressure at the time of the pulse generation is below the first set value or above the second set value can be positively detected, resulting in the prevention of abnormal burns and the improvement of the burning efficiency.
